One-Stop Sourcing: Sand Casting, Aluminum Die Casting & Fabrication Assembly
Heavy Sand Casting Up to 40 Tons • Aluminum High-Pressure & Gravity Die Casting • Turnkey Structural Fabrication & Sub-Assembly
Consolidate your entire metal manufacturing procurement through a single, accountable Indonesian partner. Through our established sister company, PT. Zenith Allmart Technindo (ZAT — zat.co.id), we provide comprehensive contract sourcing for heavy sand casting components up to 40 tons, high-pressure and gravity aluminum die casting, and full structural sheet-metal fabrication. Most critically, all chemical verification, 3D CMM metrology, and quality governance are managed under PT ZAP's audited ISO 9001:2015 and PED certified quality systems.
PT. Zenith Allmart Precisindo (ZAP) × PT. Zenith Allmart Technindo (ZAT)
Established in 2006, ZAT operates as ZAP's specialized contract manufacturing and heavy sourcing partner with offices in Green Lake City (Tangerang) and Taicang City (Jiangsu, China) — unlocking massive casting scale with guaranteed European/US export quality.
Heavy Sand Casting (Up to 40 Tons Single-Piece)
While PT ZAP's investment casting foundry excels in high-precision, thin-walled, intricate geometries up to 100 kg, our sister company ZAT handles massive sand casting parts from 500 kg up to 40 metric tons. Capable of resin sand and furan sand molding with automated sand reclamation systems.
- ✔ Ductile Iron (FCD 450, FCD 500, FCD 600) & Grey Iron (FC 200, FC 250, FC 300)
- ✔ Carbon Steel, High-Manganese Steel & Heavy Marine Bronze Alloys
- ✔ Applications: Heavy pump volutes, split-case pump casings, turbine housings & press beds
- ✔ Integrated heavy rough & finish CNC boring, planing, and gantry milling
Aluminum Die Casting (High-Pressure HPDC & Gravity GDC)
For lightweight structural, electrical, and thermal applications, ZAT delivers high-volume aluminum die casting with tight dimensional control, superior surface cosmetics, and high pressure-tightness against porosity.
- ✔ Cold-chamber High Pressure Die Casting (HPDC) machines up to 1600 tons locking force
- ✔ Gravity Die Casting (GDC / tilt pouring) for thicker, heat-treatable structural parts
- ✔ Alloys: ADC12, A380, A356, AlSi9Cu3, AlSi10Mg with T5/T6 heat treatment
- ✔ Secondary CNC flash trimming, shot blasting, and automated leak testing
Turnkey Sheet Metal, Structural Fabrication & Sub-Assembly
Beyond casting, ZAT operates comprehensive metal forming and welding fabrication facilities equipped with heavy hydraulic shearing machines, CNC press brakes, certified GTAW/GMAW welding stations, and clean sub-assembly cells.
- ✔ Hydraulic plate shearing and CNC press brake bending up to 320 tons
- ✔ ASME IX / AWS D1.1 certified welders for stainless, carbon steel, and structural alloy
- ✔ Custom machining fixtures, inspection checking jigs, and testing rigs
- ✔ Complete mechanical sub-assembly including bearings, seals, fasteners, and functional testing
Strict Quality Control Under PT ZAP Metrology & Laboratory
The critical differentiator of our one-stop sourcing model: customers do not deal with fragmented third-party subcontractors. Every sand casting melt, aluminum batch, and fabricated assembly is inspected and approved under PT ZAP’s certified quality management system.
- ✔ Chemical composition verification via SPECTROMAXx Type M Optical Emission Spectrometry
- ✔ 3D CMM inspection (Mitutoyo & ZEISS) verifying tight tolerances, concentricity & true position
- ✔ In-house ASNT Level II certified NDT inspection (PT, UT, MT) & mechanical tensile/hardness testing & accredited Charpy testing
- ✔ Complete EN 10204 3.1 inspection certification and unified warranty liability
